Although the Great East Japan Earthquake occurred on March 11, 2011, identification of victims is still ongoing. Typically, mitochondrial DNA (mtDNA) is performed when it is difficult to identify an individual using nuclear DNA. In Japan, samples from criminal investigations are subjected to nuclear DNA testing at the Scientific Research Institute belonging to each prefectural police headquarters, while all mtDNA tests were originally conducted at the National Research Institute of Police Science. However, the appraisal work using mtDNA became more time-consuming as the number of target samples increased. Because our department is capable of performing mtDNA testing, the Miyagi Prefectural Police requested that our department perform mtDNA testing. Specifically, we focused on 16 individuals as putative candidates for 11 unidentified human remains; efforts to identify these remains were performed using samples from 20 relatives. These efforts positively identified six victims. This included confirmation that one corpse had originally been identified incorrectly. Although disasters of a similar scale can strike Japan again, there are limited facilities that can consistently perform mtDNA testing. Expensive sequencing machines and properly trained operators are essential for mtDNA testing, but they cannot be established at the forensic departments of all medical schools. There is thus an urgent need to establish core facilities at appropriate sites, such as Tohoku University in the Tohoku Region, to build a mtDNA testing system suitable for the aftermath of any disaster.
The novel coronavirus disease (COVID-19) pandemic has spread throughout the world. Poor mental health has been reported among healthcare professionals responding to COVID-19. However, no study has examined the impact of COVID-19-related workplace bullying or patient aggression on the mental health of healthcare professionals during the COVID-19 outbreak. This study examined the prevalence of COVID-19-related workplace bullying and patient aggression and its association with psychological distress among healthcare professionals during the COVID-19 outbreak in Japan. This was a cross-sectional study conducted from May 22 to 26, 2020, inviting participants (n = 1,421) from an online survey of full-time employees. We limited the sample to healthcare professionals for further analyses. Using an online self-report questionnaire, workplace bullying and patient aggression related to COVID-19 was measured using nine items with dichotomous response options. Psychological distress was measured using the Japanese version of Brief Job Stress Questionnaire. Among 1,032 participants (72.6%) who completed the survey, 111 healthcare professionals were identified. Among them, 19 participants (17.1%) had experienced any COVID-19-related workplace bullying or patient aggression: 11 participants (9.9%) had experienced any workplace bullying and 12 participants (10.8%) had experienced any patient aggression. Multiple linear regression analysis showed that any bullying or patient aggression related to COVID-19 significantly correlated with psychological distress. It was suggested that a non-negligible proportion of participants experienced workplace bullying or patient aggression related to COVID-19. Preventing and reducing workplace bullying and patient aggression may be effective in improving mental health of healthcare professionals during the COVID-19 outbreak.
We herein present the case of a 45-year-old diabetic woman who developed diabetic ketoacidosis following the administration of dapagliflozin, a sodium-glucose cotransporter 2 (SGLT2) inhibitor. The patient had been diagnosed with diabetes three years previously and was being treated with multiple daily injections of insulin. Metformin hydrochloride and dapagliflozin were added seven months and 11 months later, respectively. Her clinical course was uneventful until the onset of influenza. She then discontinued insulin and oral medications voluntarily. On arrival at the hospital, she was found to be in a state of ketoacidosis, and promptly received insulin and saline infusion. In retrospect, the initial amount of glucose infused was insufficient, and the hypoglycemia was thought to have been prolonged. This phenomenon may also have affected her long-term urinary glucose excretion. Her urinary L-type fatty acid-binding protein (L-FABP) level was found to be markedly elevated (48.8 μg/g·Cr, reference value < 8.4 μg/g·Cr) as was her urinary β2-microglobulin level (9,230 μg/L, reference value < 230 μg/L). Patients with SGLT-2 inhibitor-associated diabetic ketoacidosis often exhibit protracted hyperglycosuria, in which acute proximal renal tubular dysfunction is considered to be etiologically implicated.
A 38-year-old male was admitted to our hospital for arthralgia, fever, skin rash, and purpura. He was diagnosed as having adult-onset Still’s disease (AOSD) based on Yamaguchi’s criteria. Skin biopsy revealed immunoglobulin A (IgA) vasculitis. He was also found to have anti-cyclic citrullinated peptide (CCP) antibody-positive inflammatory arthritis on a shoulder joint, however he did not fulfill classification criteria for rheumatoid arthritis. Elevated serum cytokine such as serum IL-18 supported the diagnosis of AOSD. His symptoms improved with 40 mg of prednisolone plus cyclosporin A (200 mg/day). Two years after hospitalization, AOSD was relapsed with pleurisy and hyperferritinemia. Finally, he was diagnosed with multicyclic systemic type of AOSD complicated by IgA vasculitis and seropositivity of anti-CCP antibody. Clinicians need to consider the complication of multiple rheumatic diseases, even if the disease-specific autoantibody is positive.
The impact of histologic subtype on definitive radiotherapy for patients with locally advanced cervical cancer remains unclear. The aim of this retrospective analysis was to assess clinicopathological findings and clinical outcome by histological type in patients with stage IIB-IVA cervical cancer. Ninety-two patients with stage IIB-IVA [International Federation of Gynecology and Obstetrics (FIGO) 2008] cervical cancer, who underwent definitive radiotherapy between 2013 to 2018, were identified as eligible for this study. The clinical information of the eligible patients was obtained from medical records of our hospital. Seventy-eight patients underwent concurrent chemoradiotherapy, and the remaining 14 patients received radiotherapy alone. Of 92 patients, 83 had squamous cell carcinoma (SCC) and 9 had non-SCC histology. Progression-free survival (PFS) rate of patients with non-SCC was significantly worse than of those with SCC (2-year PFS: 62.0% vs. 12.5%, p = 0.0020), but overall survival (OS) rate did not statistically differ between the two subtypes (2-year OS: 82.4% vs. 62.5%, p = 0.2157). Pelvic failure-free (PFF) rate of patients with non-SCC histology was significantly worse than of those with non-SCC (2-year PFF; 88.2% vs. 25.0%, p < 0.0001). In univariate analysis, non-SCC histology was associated with PFS rate, although there was no association with OS rate. In multivariate analysis, non-SCC histology and lymph node metastasis were independent prognostic factors for shorter PFS. In patients with stage IIB-IVA cervical cancer who underwent definitive radiotherapy, patients with non-SCC showed significantly worse PFS rate than those with SCC.
The third wave of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is causing damage all over the world, especially in Pakistan and India. Although vaccines are available and preventive measures are being taken, but SARS-CoV-2 is unstoppable. Currently, there are around 841,636 positive cases in Pakistan and 18,429 deaths, whereas, in India, both are high. From April 8th to 12th, 2021, nasopharyngeal swabs of 190 patients were submitted to PRL (PACP) lab for the SARS-CoV-2 testing, and blood samples were collected at the Mayo Hospital lab for ferritin, D-dimers, lactate dehydrogenase (LDH), and C-reactive protein (CRP) testing. This study observed that coronavirus disease 2019 (COVID-19) was more likely in individuals aged 51-60 than 61-70. In addition, our study found that COVID-19 patients exhibited a statistically significant increase in levels of ferritin, D-dimers, LDH, and CRP. In addition, this study found that COVID-19 patients had significantly higher levels of ferritin, D-dimers, LDH, and CRP. Our study revealed that SARS-CoV-2 relapsed. Furthermore, we concluded that these biochemical parameters are useful indicators for severity of COVID-19.
A number of genome-wide association studies have investigated sleep phenotypes and disorders in humans. However, the contribution of genetic variation to sleep problems in Japanese populations has remained unclear. Sleep-onset problems are the most common symptom of insomnia. Here, we examined the relationship between single nucleotide polymorphisms (SNPs) of BMAL1 (ARNTL1), CLOCK, CRY1, CRY2, and PER2, which are genes involved in the clock mechanism, and sleep-onset problems in a Japanese general population. This study included 1,397 subjects aged ≥ 40 years who participated in an annual health check-up in Yamagata Prefecture. A total of 80 SNPs of 5 circadian clock genes were analyzed. Multivariate logistic regression analyses identified variant rs11113179 in CRY1 and variants rs1026071 and rs1562438 in BMAL1 as genetic risk factors for sleep induction disorder. These findings suggest that CRY1 and BMAL1 polymorphisms are related to sleep-onset problems in a Japanese general population. However, none of the SNPs remained significant at a stringent level of multiple correction.
